You don't need more space. You need the drive to actually keep up. This 2.5-inch, 2.4TB SAS drive spins at 10,000 RPM and talks over a 12Gb/s SAS link — that's a meaningful step above a 7.2K SATA unit when your workload is transaction-heavy or I/O-bound. It drops into a ThinkSystem bay as a hot-swap, so you swap it in without a service window. The 512e sector format lines up with current Lenovo controller firmware. If your database or virtualisation host is stalling on disk and the spec says SAS 12Gb, this is the drive that removes the bottleneck
